Over the past decade, spontaneous coronary artery dissection (SCAD) has emerged as an important cause of myocardial infarction, particularly among younger women. The pace of knowledge acquisition has been rapid, but ongoing challenges include accurately diagnosing SCAD and improving outcomes.

In this study, we used a combined imaging strategy, intravascular ultrasound (IVUS) and optical coherence tomography (OCT), in 8 patients with SCAD. The diagnosis of SCAD required the visualization of an intimomedial membrane with a double-lumen or …

2012年5月31日 · Consequently, the diagnosis of SCAD increasingly relies on IVUS, which can identify the presence and extent of medial hematoma. The rarity and poor survival of SCAD limits data on the best available treatment options. Medical therapy of SCAD is appropriate for patients with resolution of symptoms and limited disease.

2010年10月1日 · IVUS is uniquely useful to differentiate atherosclerotic disease from SCAD in cases with ambiguous coronary angiography and to determine the morphology and the extension of dissection. 3 Moreover, if stenting is chosen as a treatment, IVUS is invaluable in confirming correct guide wire placement before stenting (risk of false-lumen stenting ...

Spontaneous coronary artery dissection (SCAD) is a rare non-atherosclerotic cause of acute coronary syndromes defined as non-iatrogenic, non-traumatic separation of the coronary artery wall. The most common profile is a middle-aged woman between 44 and 53 years with few cardiovascular risk factors.

2020年11月25日 · Spontaneous Coronary Artery Dissection (SCAD) may be at the origin of up to 25% of acute coronary events in women <50 yo with no or few risk factors. The diagnosis of SCAD is challenging and in some cases it may be ascertained only by intracoronary imaging such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT).

Spontaneous coronary artery dissection (SCAD) is recognized as an important cause of acute coronary syndrome (ACS) leading to myocardial infarction (1, 2, 3, 4). It is caused by hematoma formation within the tunica media of the coronary vessel wall, leading to the development of a false lumen that tracks both longitudinally and circumferentially.

We observed a higher cardiovascular metabolic disease burden associated with SCAD than literature suggests. Additionally, IVUS use in SCAD was associated with serious complications, regardless of race or gender. Further studies are needed to refine patient selection and management strategies for IVUS in SCAD.

Intravascular imaging (IVI)—initially intravascular ultrasound (IVUS) and more recently and more precisely optical coherence tomography (OCT)—has been instrumental in understanding the pathophysiologic morphology that underlies acute coronary syndromes (ACS).

2020年7月11日 · Intracoronary imaging has a vital role to play in the diagnosis and management of SCAD patients. Interventional cardiologists should be well versed with the findings on IVUS and OCT to diagnose SCAD and utilize it for optimization of PCI. However, it is important to exercise caution in performing intracoronary imaging and follow safe practices.
